convert string to json in matlab

To convert a string to a JSON object in MATLAB, you can use the jsondecode function. This function parses a JSON-formatted string and returns a MATLAB struct with the corresponding field names and values.

Here's an example:

main.m
% string with JSON data
jsonString = '{"name": "John", "age": 30, "city": "New York"}';

% decode the string and create a struct
jsonObj = jsondecode(jsonString);

% access the struct fields
disp(jsonObj.name); % outputs 'John'
disp(jsonObj.age); % outputs 30
disp(jsonObj.city); % outputs 'New York'
301 chars
11 lines

In the example above, we first define a string variable jsonString with some JSON-formatted data. We then pass this string to the jsondecode function, which returns a struct object containing the parsed data.

We can then access the fields of the struct using the normal dot notation. In this example, we print the name, age, and city fields to the console using the disp function.
